🚀 Dolphin TensorRT-LLM Demo

✅ Introduction

The Dolphin model employs a Swin Encoder + MBart Decoder architecture. In the HuggingFace Transformers Config, its architectures field is specified as "VisionEncoderDecoderModel". Dolphin, Nougat, and Donut share the same model architecture. TensorRT-LLM has already supported the Nougat model. Following Nougat's conversion script, we have successfully implemented Dolphin on TensorRT-LLM.

Note: prompt_ids MUST be of int32 type, otherwise TensorRT-LLM will produce incorrect results.

🛠️ Installation

We only test TensorRT-LLM 0.18.1 on Linux.
